F GUMMING; IOWA- GOLLAIPSIIBLE AWNING Application filed August 24, 1931. Serial No. 558,990.

It is the general practice at the present time to employ as a sun shade for use on implements such as tractors the ordinary folding umbrella of relatively large size.

These are objectionable in that the central space under the umbrella is necessarily occupied by the umbrella standard which is connected with the tractor so that the ope'ratorof the tractor cannot occupy a position centraliy beneath the umbrella.

The object of my invention is to provide a collapsible awning device of simple, durable and inexpensive construction andespecially adapted for use on tractors or the like and in which the upright supports for the awning cover when in use is yieldin'gly held in taut condition and is firmly braced on all sides against either up or down movement caused by wind pressures.

My invention consists in the construction,

5 arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and

. illustrated in the accompanying drawing, in which:

Figure 1 shows an end elevation of a collapsilole awning embodying my invention in its extended position.

Figure 2 shows a similar view showing the same collapsed.

Figure 3 shows a side elevation of my improvide awning in an extended position, the awning cover being illustrated by dotted lines; and

Figure 4 shows an inverted plan view of my improved collapsible awning in its extended position, the dotted lines showing the position of the parts when the awning is collapsed.

Referring to the accompanying drawing, I have used the numeral 10 to indicate the main supporting bar, consisting of a straight horizontal central portion and upright end portions. These upright end portions may be attached to a tractor or other support in any ordinary manner, and this forms ofmy present invention.

' The awning cover supporting mechanism at each end of the supportii'ig bar is the same, and it will be necessary to describe only one of these mechanisms. Shdabiy mounted upon the supporting bar is a collar 11, having pivoted thereto two awning supporting ribs 12 normally extended laterally and toward the adjacent end or the supporting bar, but capable of folding up to position substantially parallel with the supporting" bar, as shown by dotted lines in Figure 4. 1

7 To e'ach'of these ribs is pivoted a brace bar 13 near the central portion of the rib. This brace bar i extended downwardly,- and the other end is pivotally connected to the adjacent upright portion of the upporting bar.

no part On each side of the awning I have provided 7 a bar 14 pivoted to the outer end of both or the supporting ribs 12, and also to the outer end of each of the supporting ribs 12 is a flexible wire 15, the central portion of which is connected to the adjacentupright ortion a of the supporting" bar. The awni g over, which is made' f flexible material, is connected atits side edges to the bars 14 and at it'send edges to the wires 15.

Pivotally attached to the collar 11 is acoutr'a'etile coil spring 16, the outer end ofwhic'h is'c-ouneoted to a collar 1-? elidably ouuted upo the sup orting bar and adjustahiy clamped in position on the supportingbar Io-ya set screw 18. y

in practicaloperation, and assunihr" that the awning is in open position, itis o 'vious that the body portion or the awning will be tautl' stretched over the awning frame because of the sprin is applying constant pressure tending to force the outer ends of the ribs in a direction from the main supporting bar, and 'byfthis means the cover i's stretch-ed in all directions outwardly. The two side edges of the awni are prevented from flapping in the wind by means of the bars 14 to which they are connected, and the end edges are prevented from flapping-in the wind by means of the wires 15.

I These wires 15 er-.Eonn the additional function of serving as braces to prevent upward movement of the side edges of the awning cover, and they also support the ends of the awning cover that extend downwardly on the outer side of the upright portions of the supporting bar.

When it is desired to collapse the awning, the operator simply grasps the two sliding collars 11 and moves them toward each other, whereupon the parts will assume the position shown by dotted lines in Figure 4, with the bars 14:, the ribs 12 and the braces 11 all substantially parallel with the sides of the supporting bar, and the awning may be held in this collapsed position by a strap or other means tied around it.

In some instances it is desirable that when collapsing the cover, the tension of the spring 16 shall be released in order to make it easier to collapse it, and at the same time to relieve the springs of tension, and this may be done by simply releasing the set screws 18, so that the springs and the collars 17 travel with the sliding collar 11.

I claim as my invention:

1. A collapsible awning frame comprising a supporting bar, a pair of ribs at each end of the supporting bar, each rib being pivotally and slidingly mounted on the supporting bar, a brace pivoted to each rib and alsoto the supporting bar, said ribs being swingable from a position substantially parallel with the supporting bar to a position inclined laterally and away from the adjacent end of the supporting bar, means for applying yielding pressure to the ends of said ribs that are pivoted to the supporting bar in a direction tending to move them toward the ends of the supporting bar, said frame adapted to support a flexible awning cover attached to the outer ends of the said ribs.

2. A collapsible awning frame comprising a supporting bar, a pair of ribs at each end of the supporting bar, each rib being pivotally and slidingly mounted on the supporting bar, a brace pivoted to each rib and also to the supporting bar, said ribs being swingable from a position substantially parallel with the supporting bar to a position inclined laterally and away from the adjacent end of the supporting bar, means for applying yielding pressure to the ends of said ribs that are pivoted to the supporting bar in a direction tending to move them toward the ends of the supporting bar, a rigid bar on each side of the awning pivoted to the outer end of said ribs, said frame adapted to support a flexible awning cover attached to the outer end of the ribs and to said rigid bars.

3. A collapsible awning frame comprising a supporting bar, a pair of ribs at each end of the suporting bar, each rib being pivotally and slidingly mounted on the sup porting bar, a brace pivoted to each rib and also to the supporting bar, said ribs being swingable from a position substantially parallel with the supporting bar to a position inclined laterally and away from the adja cent end of the supporting bar, means for applying yielding pressure to the ends of said ribs that are pivoted to the supporting bar in a direction tending to move them toward the ends of the supporting bar, a rigid bar on each side of the awning pivoted to the outer end of said ribs, said frame being adapted to support a flexible awning cover attached to the outer end of the ribs and to said rigid bars, and a flexible brace attached to a central portion of each of said ribs and extended inwardly and downwardly and attached to said supporting bar.

4. A collapsible awning frame comprising a supporting bar having a straight central portion and upright end portions, a collar slidingly mounted on each end of the supporting bar, two ribs pivoted to each collar, a brace pivoted to each rib and extended downwardly and toward the supporting bar and pivoted thereto, a contractile coil spring attached to each collar, and means for ad justably securing it to the supporting bar.

5. A collapsible awning frame comprising a supporting bar having a straight central portion and upright end portions, a collar slidably mounted on each end of the supporting bar, two ribs pivoted to each collar, a brace pivoted to each rib and extending downwardly and toward the upright portion of the supporting bar and pivoted thereto, and means for adjusting said collars longitudinally of the bar whereby the ribs may be swung from a position substantially parallel with the supporting bar to a position inclined laterally and away from the adjacent end of the supporting bar.
